DESCRIPTION

This disclosure, its aspects and implementations, are not limited to the specific components or assembly procedures disclosed herein. Many additional components and assembly procedures known in the art consistent with the intended electronic cigarette and/or assembly procedures for an electronic will become apparent for use with implementations of electronic cigarettes from this disclosure. Accordingly, for example, although particular electronic cigarettes are disclosed, such electronic cigarettes and implementing components may comprise any shape, size, style, type, model, version, measurement, concentration, material, quantity, and/or the like as is known in the art for such electronic cigarettes and implementing components, consistent with the intended operation of an electronic cigarette.

Contemplated herein are various embodiments of electronic cigarettes. Unless otherwise specified, the electronic cigarettes contemplated as part of this disclosure may comprise various elements and features of electronic cigarettes known in the art, such as but not limited to batteries, vaporizers, heating elements, processors, and the like. Embodiments of electronic cigarettes described herein offer numerous advantages and solve various problems common to conventional electronic cigarettes. For example, a heat sink proximate to or in combination with the mouthpiece is configured to cool down the temperature of the vapor inhaled by the user, thus providing a safer and more satisfactory vaping experience. By way of another, non-limiting example, utilizing one or more thermistors proximate the oven or heating assembly and operably coupled to a processor allow a processor to determine when a vaporizer is in use and adjust the temperature of the oven or heating assembly to accommodate the increase of ambient air within the system.

FIGS. 27-38 depict various views of a non-limiting embodiment of an electronic cigarette 50. One or more embodiments of an electronic cigarette 50 comprise a mouthpiece 60 adapted to detachably couple to the electronic cigarette. A mouthpiece 60 may comprise a heat sink 65 and a mouthpiece opening 61. More particularly, a mouthpiece 60 may comprise an external mouthpiece opening that, when coupled to the housing 54 of the electronic cigarette 50, is in fluid communication with a vapor passage 55 within the housing 54. In one or more embodiments, the at least a portion of the heat sink 65 is extends outward from an external cover of the mouthpiece 60. Accordingly, a mouthpiece 60 may be configured to partially nest within a recess 58 on the housing 54. For example, in the non-limiting embodiment shown in FIG. 27, the housing 54 comprises a housing recess 58 on a top or first end of the housing 54. In other embodiments, the housing recess 58 may be positioned elsewhere with the vapor passage 55 extending to the housing recess 58. The heat sink 65 may comprise a depth such that the heat sink 65 interfaces with a wall 57 of the housing recess 58 and an edge of the external cover interfaces with a top edge 59 of the housing 54. According to some aspects, the wall 57 of the housing recess 58 comprises a silicone covered steel wall 57 and the mouthpiece comprises one or more magnets 68 embedded in the heat sink 65 (shown in FIGS. 31 and 32) and adapted to magnetically couple the mouthpiece 60 to the housing 54. In some embodiments, the mouthpiece 60 is separate from the heat sink 65. That is, the heat sink 65 may be removed from or coupled to the electronic cigarette independent of the mouthpiece 60.

One or more embodiments of a mouthpiece 60 comprise a vapor channel 70 recessed in the heat sink 65. The vapor channel 70 is adapted to allow fluid communication from the vapor passage 55, through the vapor channel 70, to the external mouthpiece opening 61. In such an embodiment, interfacing between the heat sink 65 and the wall 57 of the housing recess 58 allows fluid communication between the vapor passage 55 and the external mouthpiece opening 61 only through the vapor channel 70 recessed within the heat sink 65. In a non-limiting embodiment, a vapor channel 70 comprises an entry point 69 aligned with the vapor passage 55 when the mouthpiece 60 is coupled to the housing 54. The vapor channel 70 may extend from the entry point 69 towards as end 62 of the mouthpiece distal or opposite the external mouthpiece piece opening 61 before reversing course and extending to the external mouthpiece 61. More particularly, the vapor channel comprise two first arms 71 branching from the entry point 69 and meeting proximate the end 62 of the mouthpiece 60 distal the external mouthpiece opening 61, and two second arms 72 branching from the end 62 of the mouthpiece distal the external mouthpiece opening 61 and meeting proximate the mouthpiece opening 61 to allow fluid communication between the vapor passage 55 and the external mouthpiece opening 61.

One or more embodiments of an electronic cigarette 50 further comprise a vapor passage 55 positioned within the housing 54 and adapted to allow fluid communication between the oven, heating assembly 75, or vaporizer and the external mouthpiece opening 61. FIG. 28 shows a cross sectional view taken along line W-W of a non-limiting embodiment of an electronic cigarette 50 comprises a vapor passage 55 extending from the heating assembly 75 to the wall 57 of the housing recess 58. The oven, heating assembly 75, or vaporizer may comprise any oven, heating assembly, or vaporizer known in the art. Vapor from the oven, heating assembly 75, or vaporizer is caused to be drawn up through the vapor passage 55 when a user draws air from the mouthpiece opening 61.

One or more embodiments of an electronic cigarette comprise a temperature sensor, such as but not limited to a thermistor 88 (shown in FIG. 39). The temperature sensor may be positioned within the housing 54 proximate the heating assembly 75. In some embodiments, the temperature sensor is configured to detect an ambient air temperature when the heating assembly is activated and a temperature of air drawn into the heating assembly when a user inhales or otherwise sucks through the opening 61 of the mouthpiece 60. According to some aspects, a temperature sensor is positioned between a stainless steel oven or other oven of the heating assembly 75 and the plastic body or other housing 54 of the electronic cigarette 50. The temperature sensor may comprise a first end exposed, which detects the ambient air when the oven is turned on as well as the temperature of any air that goes into the oven when the user inhales from the electronic cigarette. This temperature information is then communicated to a processor 90 (see FIGS. 12-13, 16-18 and 28) within the housing 54, which increases the temperature of the heating assembly 75 to quickly heat up the oven to accommodate for the lost heat by the introduction of external air. Knowing the temperature of the ambient air when the electronic cigarette 50 first turns on will set a baseline for how much the heater will have to increase the temperature once the user inhales. For example, the colder the ambient air is, the hotter the heating assembly has to get.

One or more embodiments of an electronic cigarette 50 comprise a bottom cap removably coupled to the housing 54. The bottom cap 80 may be detachably coupled to the housing proximate the oven and/or heating assembly such that the bottom cap acts as an oven lid. While the cap is referenced as a bottom cap herein, it is contemplated that the bottom cap 80 may be positioned anywhere on the housing 54 of the electronic cigarette. FIGS. 33-37 show various views of a non-limiting embodiment of a bottom cap 80. In some embodiments, the bottom cap comprises a body 81, a biased button 82 extending through the body 81, one or more button channels 84 or recesses recessed on or around the button 82, and a plurality of ball bearings 83 coupled to the button 82 such that when the button 82 is pressed the plurality of ball bearings 83 retract to the bearing channel 84 to allow a portion of the button 82 to fit within the button receiver 87, and when the button 82 is released the plurality of ball bearings 83 move outside the bearing channel or recess 84 and inhibit the portion of the button 82 from exiting the button receiver 87. The housing may comprise an internal button receiver 87 positioned to receive the one or more ball bearings to detachably couple the bottom cap 80 to the housing.

Activation of the vaporizer may be initiated through operation of a sliding switch on a side of the housing 54. The sliding switch is biased to a first, rest position and is associated with the processor within the housing 54 that controls operation of the temperature and various modes of the vaporizer. Each time the sliding switch is moved from its rest position to a second, activation position, the processor 90 (see FIGS. 12-13, 16-18 and 28) records the movement as a change in state for the vaporizer. For example, if the rest position is the “up” position for the sliding switch, each time the switch is moved down, the processor 90 changes state. A light bar on a side wall of the vaporizer housing 54 may be used to indicate both the mode and relative temperature of the oven. By non-limiting example, a first downward movement and release of the sliding switch may turn the vaporizer on and cause the light bar to flash a first, lower light of the light bar to indicate a first mode and first temperature setting for the oven. The light bar may then start to increase the quantity of the light bar that is lighted up from none of the light bar being lit to a greater amount of the light bar being lit as the temperature rises, until the light bar is lit to the first, lower light portion of the light bar is lit. A second downward movement and release of the sliding switch may cause the light bar to flash a second, medium light of the light bar to indicate the second mode and second temperature setting for the oven, and the light bar may continue in its slow increase in the light bar lighted length increasing with temperature increase until the higher temperature is reached. Subsequent downward movements and release of the sliding switch may further cause additional flashes, changes to the temperature settings for the processor and oven, and further increase in the light bar lighted length as the temperature increases until the maximum temperature setting has been reached and the light bar is fully lit. After the maximum temperature setting has been reached by downward movements and releases of the sliding switch, an additional downward movement and release of the sliding switch may cause the processor to turn the vaporizer off and allow the user to start the process of turning the vaporizer on and selecting a desired mode again.
